DETAILED DESCRIPTION

[0065] As required, a schematic, exemplary embodiment of the present chain and chain tool are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the present disclosure, which may be embodied in various and/or alternative forms. Specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.

[0066] Aspects, advantages and/or other features of exemplary embodiments of the invention will become apparent in view of the following detailed description, which discloses various non-limiting embodiments of the invention. In describing exemplary embodiments, specific terminology is employed for the sake of clarity. However, the embodiments are not intended to be limited to this specific terminology. It is to be understood that each specific member includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

[0067] Exemplary embodiments may be adapted for many different purposes and are not intended to be limited to the specific exemplary purposes set forth herein. Other non-limiting examples of such embodiments are compositions that may be used, for example, for structural components. Those skilled in the art would be able to adapt the embodiments of the present disclosure, depending for example, on the intended use of the embodiment.

[0068] Chain members for moving and/or removing material are generally designed to be used in association with a chain tool. An exemplary embodiment of such a chain tool 100 is shown on Fig.l. The exemplary embodiment chain tool 100 comprises a tool body 102 having a longitudinal axis X-X', and a chain 104 arranged about the tool body 102 and linked therebetween.

[0069] The tool body 102 comprises a generally axi-symmetric envelope 106 extending about the longitudinal axis X-X'. The envelope 106 is disposed between generally radially-extending coaxially-aligned first and second ends 108, 110 (better seen on Fig.2, hidden on Fig.l) of the tool body 102. The tool body 102 further comprises a plurality of channels 112 circumferentially defined on the envelope 106. [0070] The chain 104 comprises a plurality of chain members 114 consecutively linked therebetween. The chain members 114 are disposed on the plurality of channels 112 such that the chain members 114 are configured to be placed one following, or partially overlapping, each other, circumferentially, while advancing axially, i.e., to spiral circumferentially about the tool body 102, but not necessarily by equal increments, from the first end 108 to the second end 110.

[0071] The envelope of the tool body 102 describes a surface of revolution and any desirable profile may be used as its outline. In the exemplary embodiment of the tool body 102 as shown in Fig.l, the plurality of channels 112 defined on the envelope 106 may comprise a plurality of ridge faces 116, and a plurality of groove faces 118. The ridge faces 116 and the groove faces 118 are arranged such that the ridge faces 116 and the groove faces 118 are parallel and alternately disposed with each other. Generally, a local ridge diameter R_DL of a particular ridge face 116 is larger than a local groove diameter DG_L of any groove face 118 adjacent to the particular ridge face 116.

[0072] The tool body 102 may be solid and / or hollow, as desired. Moreover, the tool body 102 may be monolithic (as shown in Fig.l) and / or modular, as desired. Fig.2 schematically illustrates a modular tool body 202. Since the modified embodiment of the tool body 202 is generally reminiscent of the exemplary embodiment of the tool body 102, components which are similar between the modified embodiment modular tool body 202 and the exemplary embodiment tool body 102 will be annotated by similar numbers increased by 100.

[0073] The modular tool body 202 comprises a bottom lid 220 and a top lid 222 distally located from each other along the longitudinal axis X-X'. The bottom lid 220 and the top lid 222 may serve as an outer face 224 and an inner face 226 of the modular tool body 202 respectively.

[0074] The modular tool body 202 may include alternating and interfitting ridge rings 228 and groove rings 230 disposed between the top lid 222 and the bottom lid 220. The ridge rings 228 and the groove rings 230 may axially extend between the bottom lid 220 and the top lid 222 along the longitudinal axis X-X' of the tool body 202 to terminate at the top lid 222 of the tool body 202. Each of the ridge rings 228 may define a ridge face 216 thereon while each of the groove rings 230 may define a groove face 218 thereon. [0075] Fig.3 schematically illustrates a schematic modified embodiment of a chain tool 300. Since the modified embodiment of the tool body 302 is generally reminiscent of the exemplary embodiment of the chain tool 100, components which are similar between the modified embodiment chain tool 300 and the exemplary embodiment chain tool 100 will be annotated by similar numbers increased by 200. [0076] The chain tool 300 has a tool body 302 having a generally frustoconical shape, with a bottom lid 320 (seen on the bottom left of Fig.3) having a smaller bottom lid diameter R_BL than a top lid diameter R_TL of a top lid 322 of the tool body 302. Two parallel chains 304 are wrapped about the frustoconical tool body 302, starting adjacent the bottom lid 320 and spiraling away and circumferentially around the tool body 302 to terminate adjacent the top lid 322. Each chain 304 comprises a plurality of chain members 314 consecutively linked therebetween to form the chain 304

[0077] Referring to FIGS. 4A and 4B, exemplary embodiments of tool bodies 402, 404 are illustrated. The tool body 402 of Fig.4A illustrates a convex shape thereof while the tool body 404 of Fig.4B illustrates a concave shape thereof. Although the convex and concave shapes are rendered to the tool bodies 402, 404 of FIGS. 4A and 5B respectively, it is to be noted that these shapes are merely exemplary in nature and hence, non-limiting of this disclosure. Any profile may be used to form and shape the tool bodies 402, 404 depending on specific requirements of various applications. Further, complex profiles such as but not limited to, curvilinear profiles and other, not always easily defined profiles may also be imparted to give form and shape to the tool bodies 402, 404.

[0078] Referring to FIGS. 5A and 5B, an alternative embodiment of the tool body

502 is illustrated. The channels 512 of the tool body 502 include alternating peaks 514 and troughs 516 linked by sloping sidewalls 518, 520 such that the alternating peaks and troughs 518, 520 are configured to define a generally triangular, generally trapezoidal, and / or generally sinusoidal, i.e., a sloped profile in a circumferential cross-section of the tool body 502, as best seen in Fig. 5B. A local peak diameter D_P of a particular peak 514 is greater than a trough diameter D_T of any adjacent trogh 516.

[0079] Further, the channels 512 include a pitch PI defined therebetween. The pitch PI may be measured from one peak 514 to a successive or preceding peak 514. Alternatively, the pitch PI may be measured as the distance from one trough 516 to a successive or preceding trough 516. In the embodiments of FIGS. 5A and

5B, the pitch PI defined between adjacent channels 512 is equal i.e., the pitch PI may be uniform across a length of the tool body 502. However, in an alternative embodiment of the tool body 504 as illustrated in FIG. 5C, a pitch P2 between adjacent channels 512 of the tool body 504 is unequal i.e., the pitch P2 between channels 512 across various sections of the tool body 504 may be non-uniform.

Explanation to the equal and unequal pitches PI, P2 of the tool bodies 502, 504 may become clearer upon perusal of the disclosure hereinafter.

[0080] FIGS. 6, 7 and 8 show a schematic general representation of an exemplary first embodiment of a chain 604, and a first embodiment of a chain member 614 respectively. Since the first embodiment of the chain 604 is generally reminiscent of the chain 104, components which are similar between the first embodiment chain 604 and the chain 104 will be annotated by similar numbers increased by 500.

[0081] Further, since the particular embodiment of the chain member 614 is generally reminiscent of the exemplary embodiment of the chain member 114, components which are similar between the modified embodiment chain member 614 and the exemplary embodiment chain member 114 will be annotated by similar numbers increased by 500.

As best shown in Fig.8, each of the first embodiment chain members 614 comprises a first sidewall 632 and a second sidewall 634 disposed in an opposing and substantially parallel relation to each other. The first and second sidewalls 632, 634 may be separated by a member thickness Τ_Μβ · [0083] Referring to Fig.7, each of the first embodiment chain member 614 further comprises an outer side 636 and an inner side 638 laterally disposed to the first and second sidewalls 632, 634. The outer side 636 and the inner side 638 may extend into each other to further define a pair of peripheral sides 640, 642. Furthermore, the outer side 636 is provided with a first embodiment appendage 646 upstanding therefrom. The first embodiment appendage 646 is adapted for machining and removing chips from a material (not shown).

[0084] As shown in FIGS. 6 and 7, the first embodiment chain members 614 may comprise at least one keel member 648, and at least one rider member 650 linked to the keel member 648. The keel members 648 (only one keel member shown in FIGS. 6 and 7) and the rider members 650 may alternate with each other.

[0085] Turning back to Fig.l, the chain members 114 are wrapped about the envelope 106, wherein the inner side 638 of the chain members 114 is configured to abut with the envelope 106. In particular, the rider members 650 of the chain 604 are supported on the ridge faces 116 of the tool body 102, while the keel members 648 of the chain are supported on the groove faces 118 of the tool body 102.

[0086] Turning to Fig.8 and in reference with Fig.l, a width W_KM of the keel member 648 and a width W_RM of the rider member 650 correspond to a width W_R of the ridge face 116 and a width WG of the groove face 118 on the tool body 102, respectively. [0087] Although the present disclosure discloses that the rider members 650 of the chain 604 are supported on the ridge faces 116 of the tool body 102, while the keel members 648 of the chain 104 are supported on the groove faces 118 of the tool body 102, alternatively, it may be possible to support the rider members 650 on the groove faces 118, and the keel members 648 on the ridge faces 116 of the tool body 102

[0088] As shown in FIGS. 6 and 7, the sixth embodiment chain members 614 comprises a pair of connectors 652, 654 disposed between the outer and inner sides 636, 638 of each of the chain members 614. The first connector 652 may be disposed adjacent to the first sidewall 632 while the second connector 654 may be disposed adjacent to the second sidewall 634 of each chain member 614.

[0089] Further, a portion of each keel member 648 is submerged below the ridge faces 116 and supported between adjacent ridge faces 116 on the envelope 106 as shown in Fig.l. Referring to Fig.7, a depth D_K of the keel members 648 measured from a center of the connector 652 to a basal face 656 of the keel members 648 is less than a depth D_R of the rider members 650 measured from the center of the connector654to a basal face 658 of the rider members 650.

[0090] Referring to Fig.8, the two connectors 652, 654 of a single chain member 614 define therebetween a member length L_M. In the sixth embodiment chain members 614, a pin 660 is inserted through two matching and co-aligned pin through-holes or bores 662 defined in two serially aligned chain members 614, wherein each pin through-holes or bores 662 is defined in one of the two neighboring chain members 614. [0091] Referring to Fig.9, a second embodiment of the chain 904 is illustrated. The second embodiment chain 904 comprises a plurality of second embodiment chain members 914. Any two subsequent second embodiment chain members 914 are swivelly connected therebetween by a lug 964. In the second embodiment chain 904, the lug 964 is integral with one of the second embodiment chain member 914 and is insertable through a corresponding mount 968 of a preceding and / or subsequent second embodiment chain member 914. The lug 964 has at least one radial projection 970 extending away from the lug 964 and the mount 968 is shaped as to allow the at least one radial projection 970 to pass therethrough when the lug 964 is in a certain position while preventing such passage in any other position, so that the mount 968 facilitates insertion of the lug 964 when the chain members 914 are in an insertion range of positions relative to one another, and prevents insertion and / or extraction when the chain members 914 are in a securing range of positions relative to each other, as is known in the art. [0092] At least some of the plurality of second embodiment chain members 914 may be provided with an appendage 946 on and/or about an outer side 936 thereof that may accommodate functional means for performing desired functions, as is well known in the art.

[0093] Attention is presently drawn to Fig.10, showing a schematic illustration of a third embodiment of a chain 1004. Since the third embodiment of the chain 1004 is generally reminiscent of the first embodiment of the chain 604, components which are similar between the third embodiment chain 1004 and the first embodiment chain 604 will be annotated by similar numbers increased by 400.

[0094] The third embodiment chain 1004 comprises a plurality of third embodiment chain members 1014.

[0096] With reference to the third embodiment chain members 1014 and the fourth embodiment chain members 1114 as shown in Figs. 10 and 11 respectively, and with continued reference to the alternative embodiment of the tool body 504 of Figs. 5C and 5D, it is hereby envisioned that various lengths L_MK, L_MR, L_LK, and L_LR of the respective chain members 1014 / 1114 are configured to correspond with the varying pitches PI, P2 of the tool bodies 502 / 504 of Figs. 5A-5B and Figs. 5C-

5D. Therefore, it may be contemplated by one having ordinary skill in the art to configure chain members 1014/ 1114 with identical or different lengths such that the chain members 1014/ 1114 correspond with the uniform pitch PI or the varying pitch P2 present between the channels 512 of the tool bodies 502 / 504 of Figs. 5A- 5B and Figs. 5C-5D.

[0097] Attention is presently drawn to Fig.12, showing a schematic illustration of a fifth embodiment of a chain 1204. Since the fifth embodiment of the chain 1204 is generally similar to the first embodiment of the chain 604, components which are similar between the fifth embodiment chain 1204 and the first embodiment chain 604 will be annotated by similar numbers increased by 600. The fifth embodiment chain 1204 comprises a plurality of fifth embodiment chain members 1214. In the fifth embodiment of the chain 1204, there is at least one keel member 1248and at least one rider member 1250. In the fifth embodiment of the chain 1204, the keel members 1248as well as the rider members 1250 are shown to be provided with an appendage 1246 on or about an outer side (not shown) and/or a first and/or a second sidewall thereof that may accommodate functional means for performing desired functions, such as a cutting insert 1272. However, keel members 1248 and/or rider members 1250 may alternatively be provided with appropriate appendages (not shown). In the fifth embodiment of the chain 1204, the appendage 1246 may accommodate thecutting insert 1272 within a pocket, as is well known in the art. [0098] FIGS. 13, 14 and 15 show a schematic general representation of an exemplary sixth embodiment of a chain member 1314, a sixth embodiment of a chain 1304, and a particular embodiment of a chain tool 1300, respectively. Since the sixth embodiment of the chain 1304 as well as the sixth embodiment chain member 1314 are generally similar to the first embodiment of the chain 604 and the first embodiment of the chain member 614, components which are similar between the sixth embodiment chain 1304 and the first embodiment chain 604 will be annotated by similar numbers increased by 700. Similarly, since the particular embodiment of the chain tool 1300 is generally similar to the exemplary embodiment of the chain tool 100, components which are similar between the modified embodiment chain tool 1300 and the exemplary embodiment chain tool

100 will be annotated by similar numbers increased by 1200.

[0099] The sixth embodiment chain 1304 comprises a plurality of sixth embodiment chain members 1314. Each one of the plurality of sixth embodiment chain members 1314 comprises two generally parallel and opposing first and second sidewalls 1332, 1334 separated by a member thickness Τ_Μβ· Each of the sixth embodiment chain member 1314 further comprises an outer side 1336 and an inner side 1338 laterally disposed to the first and second sidewalls 1332, 1334. The outer side 1336 and the inner side 1338 may extend into each other to further define a pair of peripheral sides 1340, 1342. [00100] Any two subsequent sixth embodiment chain members 1314 are pivotally connected together by means of a connector 1352. In the sixth embodiment chain 1304, the connector 1352 is in a shape of a pin and a socket. On the first sidewall 1332 adjacent to the second sidewall 1334 and generally between the inner and outer sides 1338, 1336, there is disposed a socket 1374 while from the opposite second sidewall 1334, adjacent to the first sidewall 1332 and generally between the inner and outer sides 1338, 1336, there is disposed a pin 1360. The pin 1360 protrudes away from the second sidewall 1334 generally transversely thereto, while the socket 1374 is sunk into the chain member 1314 inside of the first sidewall 1332 and generally transversely thereto. [00101] The outer side 1336 is provided with a sixth embodiment appendage 1346 upstanding therefrom. The sixth embodiment appendage 1346 is adapted to chip removing machinery. The inner side 1338 has a keel 1376 disposed thereon, merging with the inner side 1338 and jutting outwardly away therefrom so as to terminate at a keel face 1378. The keel 1376 has generally parallel and opposed first and second keel flanks 1380, 1382merging with, and upstanding from, the inner side

1338 and interconnected by the keel face 1378 and generally opposed first and second keel walls 1384, 1386 extending therebetween generally transversely to the first and second keel flanks 1380, 1382. The keel 1376 is disposed generally about the center of the sixth embodiment chain member 1314 wherein the width T_M6 is defined as the distance between the first and second sidewalls 1332, 1334, and has a keel thickness T_K defined as the distance between the first and the second keel flanks 1380, 1382. The keel 1376 is flanked by generally similar rider faces 1388 of the inner side 1338. As best seen in Fig.l3C, each one of the plurality of chain members 1314 comprises a median plane M passing between the generally parallel and opposing first and second sidewalls 1332, 1334 and bisecting the sixth embodiment member thickness Τ_Μβ·

[00102] In the sixth embodiment of the chain 1304, each sixth embodiment chain member 1314 has a rider depth D_R defined as a distance from the center of the connector 1352 to the rider face 1388 of the sixth embodiment chain member 1314 and a keel depth D_K defined as the distance from the center of the connector 1352 to the keel face 1378. In the sixth embodiment of the chain 1304, the keel depth D_K is greater than the rider depth D_R.

[00103] Attention is presently directed to Fig.14. Sixth embodiment chain members 1314 are arrayed as a sixth embodiment chain 1304 by moving the first sidewall 1332 of a subsequent chain member 1314 towards the second sidewall 1334 (hidden in Fig.14) of a preceding chain member 1314. The connector 1352 then connects the preceding and the subsequent chain members 1314 together, as is well known in the art. As the sixth embodiment chain members 1314 are chained together so as to form the sixth embodiment chain 1304, median planes Mof subsequent sixth embodiment chain members 1314 are disposed parallel relative to each other. In the sixth embodiment of the chain 1304, adjacent median planes M are disposed parallel to each other displaced by a distance corresponding to the member thickness Τ_Μβ·

[00104] Referring now to Fig.15, there is shown a particular embodiment of a chain tool 1300 having a plurality of sixth embodiment chains 1304 wrapped therearound. The chain tool 1300 has a tool body 1302 having a generally cylindrical shape, with a bottom lid 1320 (seen on the bottom left of Fig.15) and an opposing top lid (not shown) of the tool body 1302. Four generally parallel chains 1304 are wrapped around the tool body 1302, starting adjacent the bottom lid 1320 and spiraling away and circumferentially around the tool body 1302 so as to terminate adjacent the top lid (not shown). Each chain 1304 comprises a plurality of chain members 1314 consecutively attached so as to form the chain 1304.

[00105] The tool body 1302 comprises an envelope 1306 extending generally axially away from the bottom lid 1320 so as to terminate at the top lid (hidden in Fig.15). The envelope 1306 describes a surface of revolution and any desirable curve may be used as its outline. The envelope 1306 of the tool body 1302 comprises parallel and alternating ridge faces 1316 and groove faces 1318 extending circumferentially around the envelope 1306. Each one of the groove faces 1318 extends between a first fence (hidden in Fig.15) and a generally parallel and opposing second fence 1390, while a consecutive groove face 1318 extends between the second fence 1390 and a consecutive first fence (not shown).

[00106] Each one of the plurality of sixth embodiment chain members 1314 has its inner side 1338 touching the envelope 1306. The inner side 1338of each chain member 1314 rides one of the ridge faces 1316 of the tool body 1302, with each one of the rider faces 1388 of each one of the inner sides 1338 touching consecutive ridge faces 1316, while each keel face 1378 is facing, but not necessarily abutting, the groove face 1318. A portion of each keel member 1348is submerged below one of the ridge faces 1316 and is supported by the first fence (not shown) and the second fence 1390 of the envelope 1306. A ridge width W_R and a groove width WG are generally similar to the member thickness T_M6, while the groove depth Go of each groove face 1318, extending radially inwardly below the ridge face 1316, is generally the difference between the keel depth D_K and the rider depth D_R.

[00107] Fig.16 shows a schematic general perspective representation of an alternative exemplary embodiment of a chain tool 1600comprising an alternative tool body 1602accommodating a plurality of a schematic, representative embodiment chain members 1614. Since the alternative embodiment of the chain

1604 as well as the alternative embodiment chain member 1614 are generally similar to the first embodiment of the chain 604 and the first embodiment of the chain member 614, components which are similar between the alternative embodiment chain 1604 and the first embodiment chain 604 will be annotated by similar numbers increased by 1000. Similarly, since the particular embodiment of the chain tool 1600 is generally similar to the exemplary embodiment of the chain tool 100, components which are similar between the modified particular embodiment chain tool 1600 and the exemplary embodiment chain tool 100 will be annotated by similar numbers increased by 1500. [00108] The tool body 1602 comprises a generally axi-symmetric envelope 1606 extending about the longitudinal axis X-X'. The tool body 1602 further comprises a plurality of channels 1612 circumferentially defined on the envelope 1606. The envelope of the tool body 1602 describes a surface of revolution and any desirable profile may be used as its outline. In the exemplary embodiment of the tool body 1602 as shown in Fig.l, the plurality of channels 1612 defined on the envelope 1606 may comprise a plurality of ridge faces 1616, and a plurality of groove faces 1618. The ridge faces 1616 and the groove faces 1618 are arranged such that the ridge faces 1616 and the groove faces 1618 are parallel and alternately disposed with each other. [00109] The chain 1604 comprises a plurality of chain members 1614 consecutively linked therebetween. The chain members 1614 are disposed on the plurality of channels 1612 such that the chain members 1614 are configured to spiral circumferentially about the tool body 1602 from the first end 1608 to a second end (hidden in Fig.16).

[00110] Fig.l7A to Fig.l7F show various forms and shapes conceivable of the seventh embodiment chain member 1614. Although some forms are illustrated herein, it is to be noted that these forms merely exemplary in nature and hence, non- limiting of this disclosure. A person having ordinary skill in the art may appreciate that various forms and configurations may be possible on the chain members 1614 for adaptation and use with the exemplary embodiment of the tool body 1602.

[00111] As best seen in FIGS. 17A to 17B, each of the chain members 1614 comprises a median plane M passing between the generally parallel and opposing first and second sidewalls 1632, 1634and bisecting the sixth embodiment member thickness Τ_Μβ· The inner side 1638 has at least one keel 1676 disposed thereon, merging with the inner side 1638 and jutting outwardly away therefrom so as to terminate at a plurality of keel faces 1678. The keels 1676 have generally parallel and opposed first and second keel flanks 1680, 1682 merging with, and upstanding from, the inner side 1638and interconnected by the keel faces 1678. Particularly referring to Fig.l7A, a single keel 1676 extends away from the inner side 1638 of the chain member 1614. The keel 1676 is disposed transversely about the median plane M such that the median plane bisects the keel thickness T_K. The keel 1676 is flanked by a pair of generally similar rider faces 1688 on the inner side 1638 of the chain member 1614. Particularly referring to Fig.l7B, two keels 1676 extend away from the inner side 1638 of the chain member 1614 with a single rider face 1688 defined therebetween on the inner side 1638 of the chain member 1614. Therefore, the rider face 1688 is disposed transversely about the median plane M such that the median plane bisects the rider thickness T_R.

[00112] As best seen in FIGS. 17C to 17D, the inner side 1638 of the chain member 1614 has a plurality of keels 1676 disposed thereon, merging with the inner side 1638 and jutting outwardly away therefrom so as to terminate at a plurality of keel edges 1692. The keels 1676 have generally inclined and opposed first and second keel flanks 1680, 1682 merging with, and upstanding from, the inner side 1638 and interconnected by the keel edges 1692. Particularly referring to Fig.l7C, the keels 1676 are flanked by generally similar rider faces 1688 on the inner side 1638 of the chain member 1614. Particularly referring to Fig.l7D, two sets of keels 1676 extend away from the inner side 1638 such that a rider face 1688 is defined therebetween. Therefore, the rider face 1688 is disposed transversely about the median plane M such that the median plane bisects the rider thickness T_R. [00113] As best seen in FIGS. 17E and 17F, each of the chain members 1614 includes a basal face 1656. The basal face 1656 includes a first slant face 1658, and a second slant face 1660 disposed in opposing relation to the first slant face such that the first and second slant faces 1658, 1660 are configured to rest upon the sloping sidewalls 518, 520 of the tool body 502 / 504, as shown in Fig. 5B. [00114] Each of the chain members 1614 further includes a keel edge 1692 defined at an intersection of the first and second slant faces 1658, 1660. The keel edge 1692 is configured to rest upon one of a peak 514 and a trough 516 of the tool body 502 / 504. More specifically, the keel edge 1692 of Fig. 17E is configured to rest upon the trough 516 of the tool body 502/ 504 while the slant faces 1658, 1660 abut the sloping sidewalls 518, 520 lying adjacent to the trough 516. Referring to Fig. 17F and Fig. 5B, it can be seen that a height H_K of the keel edge 1692 from the basal face 1656 may correspond to a difference in depth D_T of the trough 516 from the peak 514 measured along linear axis L-L'.

[00115] Similarly, with regards to the chain member 1614 of Fig. 17D, the keel edge

1692 may be configured to rest upon the peak 516 of the tool body 502/ 504 while the slant faces 1658, 1660 abut the sloping sidewalls 518, 520 lying adjacent to the peak 514. Referring to Fig. 17F and Fig. 5B, it can be seen that a depth D_KE of the keel edge 1692 from an outer end 1617 of the basal face 1656 may correspond to a difference in height H_P of the peak 514 from the trough 516 measured along linear axis L-L'. [00116] Therefore, with reference to the embodiments shown in Figs. 5A-5B, and Figs. 17E-17F, it is evident that the generally triangular, generally trapezoidal, and / or generally sinusoidal, i.e., a sloped cross-section defined by the peaks 514 and troughs 516 on the circumference of the tool body 502, 504, may thus, confirm with a shape of the basal face 1656 as defined by the first and second slant faces

1658, 1660 of the chain member 1614. Although the tool bodies 502 / 504 with the generally triangular, generally trapezoidal, and / or generally sinusoidal, i.e., a sloped cross-section is disclosed for adaptation with the slant faces 1658, 1660 of the chain members 1614, it may be noted that the profile of the tool bodies 502 / 504 and the profile on the basal face 1656 of the chain members 1614 are non-limiting of this disclosure. A person having ordinary skill in the art may contemplate various forms and shapes known in the art to impart the required profiles to the tool bodies 502 / 504 and/or the chain members 1614.

[00117] Fig.18 shows a schematic top perspective view of an exemplary seventh embodiment chain member 1614 adapted to be accommodated on the alternative embodiment of the chain tool 1600 shown on Fig.16. The outer side 1636 of at least some chain members 1614 is provided with a seventh embodiment appendage 1646 upstanding therefrom. The seventh embodiment appendage 1646 is adapted for machining and removing chips from a material (not shown). [00118] FIGS. 19, 20 and 21 show a schematic general representation of the alternative seventh embodiment chain member 1614. Since the alternative seventh embodiment chain member 1614 is generally similar to the first embodiment of the chain member 614, components which are similar between the seventh embodiment chain member 1614 and the first embodiment chain member 614 will be annotated by similar numbers increased by 1000.

[00119] As best shown in Fig.19, each one of the plurality of seventh embodiment chain members 1614 comprises two generally parallel and opposing first and second sidewalls 1632, 1634 separated by a member thickness Τ_Μβ· Each of the sixth embodiment chain member 1614 further comprises an outer side 1636 and an inner side 1638 laterally disposed to the first and second sidewalls 1632, 1634. The outer side 1636 and the inner side 1638 may extend into each other to further define a pair of peripheral sides 1640, 1642. Further, as shown in FIGS. 19 to 21 the first sidewall and the second sidewall 1632, 1634of the seventh embodiment chain members 1614 are offset along the median plane M such that the peripheral sides 1640, 1642 exhibit a tiered configuration.

[00120] As best shown in Fig.20 and Fig.21, any two subsequent seventh embodiment chain members 1614 may be pivotally connected together by means of a connector (not shown). A pin (not shown) may be inserted through two matching and co-aligned pin through-holes or bores 1662 defined in two serially aligned chain members 1614, wherein each pin through-hole or bore 1662 is defined in one of the two neighboring chain members 1614.

[00121] Fig.22 shows a schematic axial section view of the exemplary seventh embodiment chain member 1614shown on Fig.18 taken along lines XXII— XXII in Fig.20. The inner side 1638 of the chain member 1614 has a plurality of keels 1676 disposed thereon, merging with the inner side 1638and jutting outwardly away therefrom so as to terminate at a plurality of keel edges 1692. The keels 1676 have generally inclined and opposed first and second keel flanks 1680, 1682 merging with, and upstanding from, the inner side 1638 and interconnected by the keel edges 1692. Further, the inner side 1638 of the chain member 1614 has a plurality of rider faces 1688 disposed thereon. The keels 1676 are disposed on one portionl691of the inner side 1638 while the rider faces 1688 are disposed on another portionl693of the inner side 1638.

[00122] Fig.23 shows a schematic perspective view of an exemplary eighth embodiment of a plurality of chain members 2314 adapted for engagement with the alternative exemplary tool body 1602of Fig.16. Since the alternative embodiment of the chain 2304 as well as the alternative embodiment chain member 2314 are generally similar to the first embodiment of the chain 604 and the first embodiment of the chain member 614 respectively, components which are similar between the alternative embodiment chain 2304 and the first embodiment chain 604will be annotated by similar numbers increased by 1700. [00123] The outer side 2336 of the eight embodiment chain members 2314 is provided with an eight embodiment appendage 2346 upstanding therefrom. The eighth embodiment appendage 2346 is adapted for machining and removing chips from a material (not shown), such as a cutting insert 2372. However, alternate eight embodiment chain members 2314 may be provided with appropriate appendages

2346. In the eighth embodiment of the chain 2304, the appendage 2346 may accommodate the cutting insert 2372 within a pocket 2398, as is well known in the art. Further, the cutting insert 2372 may be releasably attached to the appendage 2346 with the help of fasteners 2394 such as screws, bolts, or other fasteners commonly known in the art.

[00124] Fig.24 shows a schematic perspective view of an exemplary ninth embodiment of a plurality of chain members 2414 adapted for engagement with the alternative exemplary tool body 1602of Fig.16. Since the alternative embodiment of the chain 2404 as well as the alternative embodiment chain member 2414 are generally similar to the first embodiment of the chain 604 and the first embodiment of the chain member 614 respectively, components which are similar between the alternative embodiment chain 2404 and the first embodiment chain 604 will be annotated by similar numbers increased by 1800.

[00125] Each of the ninth embodiment chain members 2414 may include at least one prong 2495 defined on a first periphery 2440 and at least one prong 2496 defined on a second periphery 2442. The prongs 2495 on the first periphery 2440 include matching and co-aligned pin through-holes or bores (hidden in Fig.24) whereby a pin through-hole (not shown) on the prong 2496 may be aligned to accommodate a pin 2460 therethrough. [00126] Further, the outer side 2436 of the ninth embodiment chain members 2414 is provided with anninth embodiment appendage 2446 upstanding therefrom. The ninth embodiment appendage 2446 is adapted for milling and removing chips from a material (not shown), such as a milling tool 2497. However, the alternate ninth embodiment chain members 2414 may be provided with appropriate appendages 2446 to perform desired functions as commonly known in the art. In the ninth embodiment of the chain 2404, the appendage 2446 may include internal threads (hidden in Fig.23) configured to threadedly engage with the milling tool 2497, as is well known in the art. However, the milling tool 2497 may be releasably attached to the appendage 2446 with the help of other fasteners commonly known in the art. [00127] FIGS. 25 and 26 show a schematic representation of an exemplary link attachment means 2499.Each of the ninth embodiment chain members 2414 may include atleasta pair of prongs2495defined on the first periphery 2440 and at least a pair of prongs 2496 defined on the second periphery 2442.
